    摘要: A method for providing a stacked wafer configuration is provided. The method includes bonding a first wafer to a second wafer. A filler material is applied in a gap formed along edges of the first wafer and the second wafer. The filler material provides support along the edges during a thinning and transportation process to help reduce cracking or chipping. The filler material may be cured to reduce any bubbling that may have occurred while applying the filler material. Thereafter, the second wafer may be thinned by grinding, plasma etching, wet etching, or the like. In some embodiments of the present invention, this process may be repeated multiple times to create a stacked wafer configuration having three or more stacked wafers.
